novel coronavirus
The severe epidemic is testing China and every one of us.
Today, 80174 novel coronavirus pneumonia cases have been diagnosed, 2915 people have left us.
And the rest of the world ..
The country, with perseverance and complete courage, has opened up the sky, opened its heart and cared for every Chinese and friends.
Those angels who can't express their reverence with words show the dauntless spirit to all mankind, and they want to use their own lives for everyone's lives.
At this moment, it moved everyone's softest place.
So big a country, a great 1.4 billion people, suddenly stopped boiling, quiet like a bay of autumn water.
We should believe in our greatness and China's greatness.
The epidemic is about to and will surely pass.
It will also make necessary tests and amendments to our epidemic system.
It will also make necessary amendments to the growth model of enterprises.
meanwhile
It will also make necessary changes to people's clothing, food, housing and transportation.
As a warning for the future
Do we textile people put forward new requirements for textile production? And I think after the epidemic, people should pay attention to antibacterial.
Antibacterial
The strong infectious power of the new coronavirus and its non-contact way of transmission make people all over the country have to wear masks in a few months.
It is believed that with the past of the epidemic, people will take off their masks and return to normal.
However, in addition to the new coronavirus, there are hundreds of millions of viruses and bacteria in nature, which will be a problem we have to face.
To eliminate the germs that people are exposed to every day, people have formed the habit of washing hands and faces at ordinary times; however, we can't change clothes every day and every time.
How to reduce bacteria in clothes?
Put on a kind of anti-bacterial clothes, it will certainly reduce people's chances of getting sick in life.
In the past time, people only pay more attention to underwear antibacterial
But the coat antibacterial has the same importance
Permanent antibacterial material
To achieve permanent antibacterial, mainly through the material itself, as follows:
First, say antibacterial.
Generally speaking, antibacterial is the general term of bacteriostasis and bactericidal action.
The function of Killing Microbial vegetative body and propagating body is called sterilization; the function of preventing or inhibiting microbial growth and propagation is called bacteriostasis.
The textile fabric composed of fiber, because of its porous shape and the chemical structure of polymer, is conducive to the attachment of microorganisms and becomes a good parasite for the survival and reproduction of microorganisms.
Antibacterial fabric has different degrees of antibacterial effect, which can avoid the propagation of bacteria, reduce the risk of its re spread, and eliminate the odor caused by bacteria, so as to keep the fabric clean.
At present, there are different standards for antibacterial test, such as American Standard and national standard, which are mainly divided into two categories:
One is to monitor specific values, for example, the antibacterial rate reaches 99.9%; the other is to monitor pair values, for example, pair values are 2.2, 3.8, etc.
Generally, if the value is above 2.2 or the antibacterial rate is above 90%, it is qualified.
The tested strains mainly include: Staphylococcus aureus, Escherichia coli, methicillin resistant Staphylococcus aureus MRSA, Klebsiella pneumoniae, Candida albicans, Aspergillus niger, Trichoderma globosum, pullulans, etc.
According to the different properties of the products, the requirements of the tested strains are determined.
Classification of antibacterial materials (mainly refers to antibacterial fibers):
The production of antibacterial textiles from antibacterial fibers is the main direction of development.
There are two kinds of antibacterial fibers
One is the modified antibacterial fiber which is made by adding antibacterial agent to the fiber;
Another kind of natural fiber with antibacterial function, such as some hemp, bamboo fiber, chitin and so on.
The first kind of antibacterial effect is excellent and controllable. The second category can only be said to have antibacterial effect, but the antibacterial rate is not high, only to meet the qualified standard.
The tested strains mainly include: Staphylococcus aureus, Escherichia coli, methicillin resistant Staphylococcus aureus MRSA, Klebsiella pneumoniae, Candida albicans, Aspergillus niger, Trichoderma globosum, pullulans, etc.
Among them, Staphylococcus aureus, Escherichia coli and Candida albicans are representative.
